I`ve been in receipt of Ib since OCT 08,and was told I did not need to get further med certs,It was my gp who prompted me to claim DLA as i told her of a recent experience of being bed ridden for 6 months whilst awaiting a new drug(lefludomide)to get back on my feet....I was awarded middle rate care
and higher rate mobility......
I was given DlA until march 2012...... I`d say it may be more common than we think,IB illnesses can very easily lend themselves to care and mobility issues.
